Biodiesel has received considerable attention in recent years, as it is a biodegradable, renewable and non‐toxic fuel. Microalgae have been suggested as very good candidates for fuel production because of their advantages of higher photosynthetic efficiency, higher biomass production and faster growth compared to other energy crops. Moreover, microalgae are eukaryotic photosynthetic microorganisms that can be used to produce high value compounds as carbohydrates, hydrocarbons and natural oils.
Microalgae appear to be the only source of biodiesel that has the potential to completely displace fossil diesel. Microalgae with high oil productivities are desired for producing biodiesel. The key processes involved in biodiesel production using microalgae are cultivation, harvest, and cell disruption for lipid extraction. Although all these steps are essential, the cell disruption is particularly important, as the contents of the extracted lipids are determined according to the disruption method. Therefore, the appropriate cell disruption method is important to increasing the lipid extraction efficiency.
Botryococcus braunii is a green microalga that produces hydrocarbons whose content can reach 75% of the dry biomass, has already been proposed as a future renewable source of fuel. Cell disruption methods including autoclave, osmotic shock, acid and base lyses were compared with microwaves, sonification to determine the most efficient method. Among the tested methods, the microwave oven method was identified as the most simple, easy, and effective for lipid extraction from microalgae.
